For the power of the Xiangyang cannon, until modern times, there are still people who highly admire, thinking that it is a sharp weapon for attacking the city and grabbing the land, after all, in the era of cold weapons, it can launch three hundred catties of projectiles, the range reaches Lixu, and the ground is seven feet, and it has also reached the limit that human beings want to think at that time, thinking that it will be able to crack the mountain and crack the stone, and the city wall built by rammed earth must be vulnerable.

But as long as you think about it with your brain, the thickness of the Xiangyang city wall is more than three to four zhang, and there are bricks inside and outside, and the city body and the female wall are thick, even modern artillery cannot completely destroy it with one shot. And as long as a person sits against a wall, he can avoid being harmed. In fact, the Xiangyang cannon that was blown into the sky happened to hit the tower.

And what is the tower, in fact, it is the city gate building, which is used for lookout during the war, and the drum is used to signal the time on weekdays, and the architectural form is also a wooden structure. Think about the 300-pound big stone smashed on it, it must be the wall collapsed, the house collapsed, and the ashes were annihilated. And the reason why the Mongol army relied on this thing to destroy the will of the defenders of Xiangyang, Zhao Yu thought that in fact, the Xiangyang cannon was just the last straw added to the camel's back, trapped for a long time, the defenders were desperate, and when the artillery bombarded, this far exceeded the width of the moat and ditch of Xiangyang City, and they finally collapsed.

Of course, Zhao Hao did not deny the power of the Xiangyang cannon, as a giant counterweight trebuchet, the projectile stone used in the Xiangyang cannon weighed 300 catties, the range was nearly 400 meters, and it was seven feet deep when it landed. Such a huge power can not only effectively destroy the buildings in the city, but also cause a great blow to the city defense. This powerful early artillery was not necessarily comparable to a heavy trebuchet, after all, it was a large machine that could throw hundreds of pounds of stone hundreds of meters.

But Zhao Yu believed that what gunpowder-powered artillery couldn't do, then Xiangyang artillery couldn't do it, and the only advantage of this weapon was probably that it didn't cost gunpowder. He also designed and manufactured a ballista that was better than a catapult in terms of hit rate and range, and even built a torsion catapult that was heavier than the projectile fired by the Xiangyang cannon and had a longer range, but it was still eliminated after the successful trial production of the artillery, and it was only an option under special conditions.

First of all, the Xiangyang cannon is too large, the hit rate is low, and the rate of fire is slow. In order to shoot huge stone projectiles, the Xiangyang cannon is several stories high, which is not only difficult to lay and difficult to move, but also because of the low level of Taoism in ancient times, the more huge the catapult, the lower the hit rate. Therefore, although it is known as shocking power, after the capture of Xiangyang, although the Mongols made a large-scale return cannon, but after six years of hard fighting, they completely destroyed the Southern Song Dynasty, including many arduous siege battles.

And the artillery, both in terms of adaptability to the terrain and the hit rate, is above the Xiangyang artillery. Although most of the artillery pieces were not as powerful as the Xiangyang cannon, which was several stories high, the huge size of the Xiangyang artillery also brought a lot of inconvenience and was limited by the terrain. Therefore, the Xiangyang artillery could not conquer a mountain city like Diaoyu City, and the steep terrain could not be deployed at all, which showed the huge limitations of the use of Xiangyang artillery in the terrain. Therefore, the real historical Xiangyang cannon has become a cost-effective weapon compared to artillery in the Ming Dynasty, and the Ming Dynasty is of course more inclined to use artillery.

In addition, the biggest disadvantage of trebuchets compared to artillery is not that they are less powerful, but that they are difficult to operate. Heavy trebuchets require hundreds of people to work together to throw boulders. In the Song Dynasty, there was a kind of trebuchet that could throw 90 catties of boulders and required 250 people to pull ropes together. In the European Middle Ages, a light trebuchet required twenty people to operate together, and a heavy trebuchet required a hundred people. A trebuchet like the Xiangyang Cannon that throws hundreds of pounds of stones may require 200 people to operate it together. If you add all kinds of auxiliaries, a heavy trebuchet needs to be equipped with three or four hundred people.

However, the artillery 'invented' by Zhao Yu can be operated by four people in ordinary light artillery, and the heavy artillery is only eight people, so the people used to operate a Xiangyang artillery are all on top of his artillery battalion that operates twenty heavy guns. What's more, the range of the artillery is longer than that of the trebuchet, and a trebuchet six or seven meters high is simply a target for the artillery of the defending city.

So although trebuchets are not the first time they have appeared on the battlefield, and there are also equipment in the Song army, the trebuchets of the Song army are not the same as the return cannons. After the battle of Xiangyang, when one side on the battlefield had heavy artillery firepower and battlefield advantage, Xiangyang artillery became a nightmare for the Song army on the battlefield of Song and Mongolia, and the cities were conquered under its roar, from the Yangtze River to the cliff mountain in the South China Sea, the superior sailors of the Song army were also bombarded to pieces under its blow, and finally fell like the Asian and European countries.

To put it mildly, the Xiangyang Cannon was sideways on the battlefield at that time, and its impact was also far-reaching, becoming a lingering fear for a generation of Song troops. And Zhao Yu could hardly expect everyone to have the same clear understanding as him, but he didn't expect that the New Song Army, which had been equipped with artillery for a long time, would still be so scared, and it was really ridiculous and pitiful......

Zhao Yu talked with Zhang Jin until the evening, and he already had a more comprehensive understanding of the current situation, and he already had a plan in his heart. By the time he stepped out of the carriage, the rainstorm had stopped, and the western sky was so red that it seemed to be blazing, and the soldiers were digging ditches to drain the water from the camp by the last light of day.

"Your Majesty, do you have to cross the river tomorrow?" Seeing the emperor coming, Ni Liang immediately greeted him and asked.

"How's the water going?" Zhao Yu didn't answer, but asked first.

"The river drained very quickly, and in just an hour, the submerged pontoon bridge was exposed!" Ni Liang pointed to the river.

"It seems that the downstream drainage is smooth, and there is no scene of three rivers rushing together!" As soon as Zhao Yu stretched out his hand, Tan Fei, who was with him, immediately handed over the binoculars, and when he looked forward, the pontoon bridge was indeed revealed, trembling and shaking under the impact of the river.

"Your Majesty, if you cross the river from now on, it will be Fancheng, is the Jingxiang camp located here?" Ni Liang already knew that a spy from the Secretariat had entered the camp and had been secretly discussing with His Majesty for more than half a day, but he still didn't know the situation.

"The Xiangfan battalion was stationed in Nanwanshan in Xiangyang, where the Sixth Army, the Second Cavalry Division and the Second Artillery Division were stationed. The Seventh Army is attacking Gucheng, and the Eighth Army has withdrawn from Fancheng and moved to Dengcheng. Wu Long attacked Gucheng and did not stop, Zhang Ba divided his troops to reinforce, and the road ahead was cut off by the enemy defending Fancheng. Zhao Yu briefly introduced the current situation.

"Why did he give up Fancheng?" Ni Liang said in surprise.

"It's a joke to say it, because Shi Bi put out a few Xiangyang cannons, and scared our Zhang Dutong to Dengcheng!" Zhao Hao smiled helplessly.

"What a damn thing, you retreated without a fight!" Ni Liang hated the authentic way.

"I didn't expect it to be so unbearable!" Zhao Yu said.

"Your Majesty shouldn't have relented back then, reactivated this rebel general, and beheaded him, there would be no today." Ni Liang said, "Today, he is cowardly, and his subordinates ask for an order to go and behead him, so as to enforce military discipline and boost the morale of the army." ”

"At that time, his life was for the sake of the overall situation, and he still can't be killed at the moment!" Zhao Hao sighed. He knew that what Ni Liang was referring to was that in the Battle of Yashan, the camp of Xingchao was broken by Zhang Hongfan, and Zhang Ba and others lowered their sails to surrender. In order to stabilize people's hearts, he did not immediately kill after the war, and after arriving in Qiongzhou, Zhang Shijie took the initiative to give up the right to send troops, only asking himself to treat his old subordinates well, so he reinstated several people and left them in the army to continue to serve.

"Why?" Ni Liang was very puzzled.

"Jiang Shuai has already retired, if I just arrive and behead his generals, he will be disgraced, how will he deal with himself after returning to the dynasty, the name of the Jiang family's loyal martyrs will also be destroyed, and he can only commit suicide in the name of the whole Jiang family!" Zhao Yu didn't hide his thoughts from Ni Liang, and looked at him and said.

"Your Majesty is still soft-hearted." Ni Liang listened and muttered in a low voice.

"It's not easy to be an emperor!" Zhao Hao looked at the red sky and sighed.

Zhao Hao didn't want to use thunderous means to purge the three armies, but now he no longer rules the grass head king in a corner of Qiongzhou, with a population of only one million. But it is to control thousands of miles of territory and rule an empire with a population of tens of millions, and it can no longer be willful, happy and hateful, but it is necessary to consider the overall situation, and the first thing any ruler needs is 'stability', people's stability, social stability, army stability, and official stability.

He is well aware of the Jiang family's status in the government and the opposition, and if he 'forces Jiang Cheng to death', then there will inevitably be another turmoil. And in this old minister's joint of readjusting the structure of officials, what he needs is stability, but it is not to make people feel the desolation of the birds and the dead dogs, so even if he is angry, he must take action to defend it, so that even if he wants to retreat, he must go more decently.

"And what about Your Majesty?" Ni Liang didn't have to think about how the emperor should be, he only knew that all he had to do was to listen to His Majesty's words, not interfere with His Majesty's layout.

"Stabilize the three armies, revitalize the army's heart, and conquer Xiangyang!" Zhao Yu took a deep breath, slowly exhaled turbidity, and said nine words.

"How to do it, please show your majesty!" Ni Liang said.

"Don't get tangled up in the details, don't go into the details, do your own thing." Zhao Yu looked at Ni Liang and said. He knew very well in his heart that Ni Liang was his hole card and the only barrier behind him. It was his unconditional and unprincipled obedience that made the courtiers very jealous of him, and when anyone wanted to transfer him away from his side, he categorically rejected it.

But Zhao Yu also knows that his trust is also a burden for Ni Liang, and he has to face criticism and exclusion from all parties. Although he has nothing to ask for, he cannot turn a blind eye and ignore it, he must resolutely safeguard his interests, ensure the safety of his life, and even the wealth of his descendants, and try to pull him out of the mess.

"Your Majesty is going to cross the river and attack Fancheng?" Ni Liang was stunned for a moment and asked.

"Yes, if Fancheng is not broken, it will not be enough to boost the morale of the army." Zhao Yu nodded.

"The subordinates understand, immediately arrange to cross the river, and they will go to Fancheng within two days!" Ni Liang listened to Shi Lidao, and he followed His Majesty's will like blindly obeying.

"Are you afraid?" Zhao Yu turned his face to look at him and smiled.

"Since the subordinates have followed His Majesty, they have never been afraid, and little Fancheng is nothing!" Ni Liang smiled innocently, and said indifferently......
